The fit has been further improved without causing pain in the ear canal, and the sound insulation value has also been increased. You don't have to worry about them falling out of your ears even when you toss and turn in your sleep. [High-performance filter] Reduces sound by approximately 32dB. By wearing them when you are concerned about surrounding sounds, such as during sleep, work, study, or in public places, they will block out unpleasant sounds in your ears. [Designed to fit your ears] You won't feel tired or uncomfortable in your ears even after wearing them for long periods, such as during sleep.
